Was a nailfold capillaroscopy done? That can help provide some helpful information. You didn't say if your ulcers healed quickly and for how long you've had Raynaud's. You also don't mention how young you are. So many things can cause your symptoms, both related to and unrelated to AI problems. It is very good that you don't have joint damage. I hope that you keep us updated on your labs and are getting treatment for your Raynaud's to prevent further ulceration!
